------------------------------------------------

bq.Maybe I need to make queues bigger and add more serializing threads.
Usually if I have data of 100 G and try to load this to a file mode bucket 
cache it takes quite some time. I have infact configured the Writer Threads in 
Bucket cache upto 200. Still you can see a stats saying failedblockAdditions. 
Exceptation is that in case of PCIe SSD this failure should be comparatively 
lesser but in HDD they are more. I can help with this JIRA in what ever way I 
can.
